Abstrak :
Pajanan bising merupakan salah satu faktor yang mempengaruhi gangguan pendengaran atau noise-induced hearing loss (NIHL). Pada bagian assembling PT Suzuki Indomobil Motor Plant Cakung 1 terdapat bahaya bising yang berasal dari mesin dan peralatan. Penelitian dilakukan secara cross-sectional atau potong lintang terhadap pajanan bising harian dan keluhan gangguan pendengaran dengan melihat faktor perancu berupa masa kerja, usia, pemakaian alat pelindung telinga (APT), perilaku merokok, dan hobi yang dimiliki pekerja (menembak mendengarkan musik atau radio dengan menggunakan headset atau headphone mengunjungi diskotik (dugem), dan menonton pertunjukkan konser musik rock) dengan cara mengukur pajanan dosis bising harian dan pengisian kuesioner. Berdasarkan analisis bivariat tidak ditemukan perbedaan yang signifikan antara pajanan bising harian dengan keluhan gangguan pendengaran. Selain itu juga tidak ditemukan perbedaan bermakna pada variabel perancu dengan kejadian keluhan gangguan pendengaran yang ditunjukkan dengan nilai p-value <0.05.. Perlu dilaksanakan beberapa elemen dari program, HLPP (hearing loss prevention program) terutama pemeriksaan audiometri untuk mendeteksi dini adanya gangguan pendengaran. ...... Exposure to noise is one factor that affects hearing loss or noise - induced hearing loss ( NIHL ) . On the assembling 4W unit of PT Indomobil Suzuki Motor Plant Cakung 1 there is a hazard that noise coming from the engine and equipments. The study was conducted as a cross - sectional of the daily noise exposure and hearing loss complaints to see confounding factors such as length of service, age , use of ear protective devices (APT), smoking behavior, and worker -owned hobby (shooting listening to music or radio with a headset or headphones visiting discotheques (clubbing), and watch a rock concert performance) by measuring the daily noise exposure dose and questionnaires. Based on bivariate analysis found no significant difference between the daily noise exposure with hearing complaints. It also found no significant differences in the incidence of confounding variables with complaints of hearing loss as indicated by the value of p-value of <0.05. It should be implemented some elements of the program, HLPP (hearing loss prevention program) primarily audiometric examination for early detection of hearing loss.

ABSTRACT
Background: Occupational fatigue commonly found in the workers of heavy equipment manufacturing industry. Noise below the threshold value may cause occupational fatigue as one of non-auditory effects. Occupational fatigue can be examined by checking the reaction time of the workers. This study aims to know the difference of mean reaction time in heavy equipment manufacturing industry workers whom exposed with noise under the threshold value, which grouped into three exposure groups: 60-70dB, 71-80dB, and 81-85dB. Study Method: Comparative, descriptive cross-sectional study. It is conducted to 149 male workers. Data collected by interview, physical examination, reaction time test with Lakassidaya and questionnaire of KAUPK2. The inclusion criteria for the subject are a willingness to follow the study and to sign the informed consent, age 19 ? 55 years old when the study conducted, no illness history, 8 hours working duration or without overtime, and has equal working load. The exclusion criteria is that the subject is ill when the study being conducted or recover from illness recently. Result: Kruskal Wallis statistical test is used to analyze the mean reaction time between the three exposure groups, 60-70 dB, 71-80 dB, and 81-85 dB with p value <0,001. To acknowledge which noise is significant, the Mann-Whitney test is used. The results suggest that the reaction time examination of before work, after work and the difference between, is significantly different between the groups of 60-70 dB and 71-80 dB toward the group of 81-85 dB, whereas the reaction time examination of before work, after work and the difference between, in the group 60-70 dB toward the group of 71-80 dB is not significantly different, with p value <0.05.
